Fusion Material Calculator

How to Use This Tool

Follow these steps to calculate fusion materials for your game:

1. Select your fusion type from the dropdown (Character, Weapon, Item, or Tabletop Craft Fusion).
2. Choose the material tier you are using (Common, Rare, Epic, Legendary).
3. Enter the number of materials required per fusion attempt.
4. Input your target number of successful fusions.
5. Add your base fusion success rate as a percentage.
6. Optional: Enable the pity system toggle and enter pity threshold and rate if your game uses a pity mechanic.
7. Click Calculate to see your material breakdown.
8. Use Reset to clear all inputs, or Copy Results to save your calculation.

Formula and Logic

The calculator uses these core formulas for standard fusion systems:

• Expected Base Attempts = Target Successful Fusions / (Base Success Rate / 100)
• Total Materials = Expected Attempts * Materials Per Fusion
• For systems with pity: Expected Attempts adjust to account for increased success rates after failed attempt thresholds.

Note that success rates in live games are often patch-dependent. Always check your game’s current patch notes for updated fusion rates before planning material spends.

Practical Notes

Gaming fusion systems vary widely across titles, so keep these context-specific tips in mind:

• RNG factors: Even with a 50% success rate, you may need more attempts than the expected average due to variance. Plan a 10-20% material buffer for unlucky streaks.
• Meta variations: Popular fusion paths may have adjusted rates during balance patches. High-tier competitive players should verify rates for current meta builds.
• Tabletop games: Fusion material costs often scale with character level or campaign progression. Adjust your target count based on your session’s progression goals.
• Streamers: Save calculation results to share with viewers during resource planning segments.

Why This Tool Is Useful

This tool eliminates guesswork for multiple gaming use cases:

• Gamers avoid wasting rare or premium materials on over-fusion attempts.
• Game designers balance fusion systems by testing material cost scenarios during development.
• Competitive players plan material farms ahead of ranked seasons or tournaments.
• Tabletop groups track crafting costs for campaign sessions without manual math.

Frequently Asked Questions

Does this calculator account for guaranteed fusion systems?

Some games offer guaranteed fusion after a set number of attempts (hard pity). Enable the pity toggle and enter the threshold to get accurate estimates for these systems.

Can I use this for gacha game character banners?

Yes, select Character Fusion as the type and enter the banner’s published success rate. Note that some gacha games have hidden rate increases for new players, which this tool does not factor in.

How do I adjust for patch changes?

Re-enter the updated success rate from the latest patch notes into the Base Success Rate field. The calculator will automatically recalculate your material needs.

Additional Guidance

For the most accurate results:

• Cross-check success rates with official game documentation or datamined values from trusted community sources.
• Add a 15% material buffer if you are fusing during limited-time events with unconfirmed rates.
• Tabletop players should confirm material costs with their game master before finalizing plans.
• Game designers can use the material tier multiplier display to test economy balance across rarity tiers.
